I agree that ternary can make code unreadable, especially so with the ‘?’.
I personally like the Haskel option the most, but it introduces a new
keyword ‘then’, which isn’t great either. Python’s "y if x else z" is
therefore, in my opinion, the best alternative.
Also, I found it interesting how split the Rust community was about
removing the ternary operator.
